' Specification of Letters Patent.

Patented Dec. 1.7, RS07 Application filed January 1311906. Serial No. 295,84c9i To all whom it may concern:

Be it known that I, llAROLD BINNEY, residence 10 Lexington avenue, New York'city, (post-oflice address, 1.41 Broadw sy, New York city, New Yorlg) have invented certain new and useful Improvements in 'lracker-Boards for Legato and other Effects in Pneumatic Musical Apparatus, of which the following is as ecificetion.

dome years ago it was discovered that by overlapping the )erforetions of successive notes of a, musical composition in the periorevted music rolls used for piunolas and. other instruments e smoothness of sound and. legeto e'l'iect resembling hand-playing could he produced.

The object of the present invention is to get a similer result so for as possible Without the use of overlapped perforations. To sccomplish this I prolong each of the trucker holes in the direction of the motion oi the sheet and )rovide means for adjusting or verying the length of opening of such trucker holes.

The eccon'ipenying drawings illustrate one form of the invention, Figure 1 heing a. lace View oi u'portion of ii trucker hoard provided with the present invention, omitting: various other parts of the iiistrunient which will he Well u n d erstooi l ol' the some.

The 'lrzwkei' hoard B has the/ mouths ol the Fig. 2 is a sectional view trucker ducts l) clongutcd in the direction ol' travel so to prolong the sounding ol' the note, hut the op niing oi those moui hsis udjustuhlc hy means of a slidc-plul'e which has teeth like a cone that lit into uud are adapted to partly close the mouths ol' the trucker ducts. 'lhe slide (1 is mounted so as to lHBIllOVZLlllG to more or loss open the mouths of the ducts. 'lhis movmuvnt isfprovidod for by means ()l SH'UWS and slots if, the upper surface of the slide pinto t, living llush \vilh thul ol the lJ'HC-lill hourdl) so us to l'orm fl, coulinuzuhm or purl ihoreol. Adjuslmcnt ol the pluto is illustrated as being;

unless the :nljustnblc slidcplulc effected by means of the longitudinally n1ovable slide G which runs beneath the slide plate C and provided with pins H that tend up into and. cooperate with inclined slots J in the slide C. The lengthwise movement of slide G and pins ll therefore causes the transverse 1'n( 'emenl oi the slide L and decreases or increases the length oi the mouths of the ducts i) To permit the lengthwise n'i'oveinent of the slide o where the screws F extend through-it it slotted longitudinally, as shown in dotted lines.

By the use ol' this invontiini, for example on pisnolus, org-en music rolls designed for the aeolian grand may he used on phmohis to produce legato Without any change in tho pcriorutions ol the rolls, the mouths oi the ducts i) being proloruhly uhoul ono-tonth of all inch longer than is :u pi'csmit custom This will interfere .Wil ll some lornu; oi li'ills is moved to reduce the siz of the ducts during the trill. When the performed music roll is moving; slowly, the mouths of the duels should be shorter than whcnthc paper is moving l'2l[)- idly.

It will he soon thul: the presentinvention furnishes one mums ol' poi-milling ucoliun grand music to he usod on phmolus and other piano Mayors without. iii-cutting the rolls and at the some time without tho objections that would otherwise occur in the music when used on pinholes without this imcution. To some (Xlvl'li it provides an ulli-i'uutivo lor the use of overlapping perforations, though of course it cannot provide for all the actions that occur with the proscnt {rocker holes and appropriate piunolu music.

VVhutl claim and de ire to secure by those Letters Pulcnt as lhc Lhfitlll iul l'oul ui'cs of my invention are the l' llo\\iu;

l. A trucker having duct means for adjusting their size.

2. A trucker providml \viih u series of trucker ducts and a slide for \ui' ving the openings or mouths of tho suid duels.

mouths :uid

3. A tracker provided with av series of ing a comb-shaped member the teeth of which fit into and. slide in the 111012 ths of the tracker 1(1 duets.

In testimony Wi'lGI'OOi' I have signed this speelficegion 1n the presenpeof two subscrib- 111g witnesses.
